[support-infra] Setup org wide issue template

[oliviertassinari]

Summary

This issue is similar to GitHub workflows https://github.com/mui/mui-private/issues/360 shared in the organization, but for issue templates. This should be doable with https://github.com/orgs/community/discussions/22451#discussioncomment-3236785.

Example

Always the same between repositories:

• RFC: https://github.com/mui/material-ui/blob/master/.github/ISSUE_TEMPLATE/3.rfc.yml but with a different prefix than 3. It would rank too high in the order. 7 sounds better.

There are other issue templates but none that seem that we can share.

Motivation

Discussed in mui/mui-x#11995 (comment).
